How to do Baseline correction & Multi-peak fitting of XPS/XRD/RAMAN/PL data in OriginLab Pro.
I understood every bit of the video, it helped me as a stater.
Very good
You re not good at explanation
Man he's awesome
in some xrd pattern, some peaks can be fitted in gaussian form but not others, and if i use lorentzian fit for them we can fit them, can we do that?
Thank you so much sir
Thank you
Thank you so much Sir, make more Videos like this, it will be very helpful 😊

i want to download the origin pro software without buying it
How did you assume parameter values and put in the function?
For best fitting of a curve, the distance between the data points and the fitted line/curve should be minimized. For this, we need an equation with unknown parameters that fits our data. Mainly, we require an initial/starting values for these parameters. Then we do iteration process to minimize the error. Sometimes the parameters values may fail to converge or the user defined function which don’t have pre-defined starting parameters values. In that case, you will have to supply your own starting values.
Start with your own values ...
suppose we have a curve how do u determine the parameters????

@@PlayWithScience thank you so much. Can we do it in excel
Excel has a preprogrammed feature/equations that will find the best fitting for a data set for a select number of functions.
Thank you very much Sumit 👏👏
Thanks 😊 ma'am
बहुमुखी प्रतिभा के धनी, भैया हमारे।
thanks ji
Good luck
Thanks 😊
Hey Sumit, you mentioned baseline correction for XPS spectra, maybe you can do by this method in other characterization since background in XPS spectra have a lot of information and in some cases if you subtracted directly maybe you will lose optimal results as excepted.( it could be peak symmetry, satellite peaks, plasmon loss peak etc..)
You are right. For my data we already knew about the number of peaks. This video was just an exploration of the tool. Students can explore many functions/options in this.
very sweet voice sir
Thanks 😁
Good video.
thank you
All the best
thank you
